(1) "Tab Pickup". I've never used it, don't want to use it, doubt if I will ever use it, but when I'm in the middle of my work, moving fast, lots of windows open, then bring a window to the top of the Z-order and get "Tab Pickup" and an INTERRUPTION of my work. If I had a gun and if it would do any good, I'd SHOOT the computer. I HATE "Tab Pickup". PLEASE, in Settings, make "Tab Pickup" =====>>> Optional <<<===== hopefully with default OFF. (2) Again, in the middle of busy work, I move the mouse and, presto, bingo, again, if a gun would do any good, another INTERRUPTION in my work as Firefox has a POPUP that covers what I'm trying to look at. Sometimes the popup is of a URL, a LONG URL with ~10 lines of text, and covers a LOT of the screen. Sometimes so, ASAP I have to get rid of the popup. I hate interruptions, "Tab Pickup", popups, changes I didn't ask for.
